ABSTRACT:
A method and device for the examination of a joint between a hollow steel shaft and a piece joined to the steel hollow shaft of a composite camshaft using ultrasonic examination. In the ultrasonic examination, the composite camshaft is put into a liquid and a probe of an ultrasonic search unit is inserted inside of the hollow steel shaft. The ultrasonic examination of the joint is performed from inside of the hollow steel shaft. According to the ultrasonic examination, any kind of joint of the composite camshaft is possible, because a distance from an inside surface of the hollow steel shaft to the joint is constant. In addition, since the probe does not contact the inside surface of the hollow steel shaft, the probe is not consumed due to abrasion.
